Question

Any line with a slope of zero is parallel to the
O y-axis
O x-axis
O line y = x

Answer 1

x- axis

Explanation:

We are given that any line whose slope is zero.

We have to find the line with a slope of zero is parallel to which axis.

We know that when any line is parallel to x- axis

It means y does not change with

Therefore,
`(dy)/(dx)=0`

Slope of a line which is parallel to x- axis is zero because y does not vary with x.

But when a line parallel to y - axis then slope of that line is undefined.

When line y=x

Then ,
`(dy)/(dx)=1\\eq 0`

Hence, any line with slope of zero is parallel to the x- axis.

Answer:x- axis.

Answer 2

x-axis

Explanation:

A line with a slope of zero has the same y-value everywhere, so is parallel to the line y=0, the x-axis.
